Go for fz150..im currently using a naza gtr. I rode my bike from my house in hulu kelang to kuala kubu bharu everyday using the road to ulu yam/sg tua..for 3days ive used rm24 of fuel..n due to my heavy weight, i was not able to speed climbing the hills there..not enough pickup..im now considering upgrading to a bttr cc motobike.huhu
